The Study Of WCDMA Radio Network Planning

This article analysed the effect of the algorithms of the radio resource ranagement to the performance and the parameter of the networking from the start of the basic principles of WCDMA. And it analysed the relationship of the interference, coverage, capacity and quality of the WCDMA radio network. On this basis, it combined the practice material, and introduced the process of the network planning, and do the WCDMA radio network planning, and the study of simulation, then it summed up the key poin(?)s of the wireless network planning, and introduced and anylysed the methods and Techniques of the specific implementation of the planning. The article also described the effect of the indoor coverage to the network planning, and then brang up the advi(?)e to the indoor coverage.The the main content of this article can be divided into seven parts. It The first part, introduction, it described the original and development process of 3G. Showing the necessity of sthdying 3G radio network planning though analysising of 3G mobile communication's development over the global and the mobile communication's developmengt of China. In the second part, there is description of the effect of the radio resource management algorithm to the network performance and planning, by analysising and studying the characteristics of the WCDMA system, especially study of the radio resource management algorithm. By the train of this thought, in part three, it descripted the similarities and differences between WCDMA and GSM radio network planning and special ways of WCDMA radio network planning through compairing the planning of GSM radio network. On these basis, it submitted the key point of WCDMA network planning. In the fourth part, it studied the WCDMA radio network planning by analysing the relationship of up/downlink and capacity, and the relationship of up/downlink of business and coverage, in theory analysis, based on the characteristics of self-interference of WCDMA network. Then in the fifth part, it studied the a specific case of some one city in bing given conditions, through use of the AIRCOM simulation software, and carried out the map of the simulation results of the relationship of the capacity, coverage and interference each other. In the sixth part of this article, it brang the co-(?)anning ideas of the indoor and outdoor coverage, and adviced the design proposals of the WCDMA indoor distribution system forth. As part of the full text, in the seve(?)th part of the article, I summed up the features of WCDMA radio network planning and the priorities of the future research.
